FRISCO -- Rookie Connor Williams underwent arthroscopic surgery on his right knee Wednesday. No definitive timetable is in place, but club officials are optimistic that he'll be able to return this month.

Williams has started every game at left guard this season and not missed a snap, including Monday night's loss to Tennessee when he apparently tweaked the knee at some point during the game.

"Hopefully it will be a short-term thing rather than a long-term thing," Garrett said.

Xavier Su'a-Filo and Adam Redmond will compete for the starting job in practice this week. While both are guards, Redmond is more of a center who can play guard.

While that appears to be the most likely option, moving Redmond to center and sliding Joe Looney over to guard is a possibility if the coaching staff believes that five will be stronger.

"All options are available to us," Garrett said. "We like all of our interior guys. We'll just practice this week and see how it goes."

Briefly: Eight players, including four starters, didn't practice Wednesday because of injuries. The starters were defensive end Taco Charlton (shoulder), end Geoff Swaim (knee), Lee and Williams.
